oracle提示TNS:无监听程序的解决思路

登录提示：无监听程序的解决思路

看了一下F:\oracle\product\10.2.0\db_2\NETWORK\ADMIN
无下面两个文件
tnsnames
listener

再看了一下服务
CMD->SERVICES.MSC

ORACLE本来应该有三个服务的，少了一个监听服务！



现在从另外一台机器上拷贝过来下面两个文件:
tnsnames
listener

再将里面的内容进行改一下，
现在tnsnames文件下内容为:


COGNOS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = cognos)
    )
  )

现在listener文件下内容为:
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = F:\oracle\product\10.2.0\db_2)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = F:\oracle\product\10.2.0\db_2)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )



然后再在CMD窗口中输入：lsnrctl start
提示启动成功！

再看看服务窗口，该服务启动了！
用PL/SQL登录进去，一切OK！
